Rates of women who are opting for preventive mastectomies, such as Angeline Jolie, have increased by an estimated 50 percent in recent years, experts say. But many doctors are puzzled because the operation doesn't carry a 100 percent guarantee, it's major surgery -- and women have other options, from a once-a-day pill to careful monitoring.

The Consumer Product Safety Commission says plastic hardware on Generation 2 Worldwide and ChildESIGNS cribs can break and allow the drop side to detach. In addition, the mattress supports can break away from the crib frames. Both defects create gaps where a small child can be trapped and suffocate or strangle.

The agency has received three reports of children who died after getting trapped in gaps between the drop sides of their cribs and their mattresses.

An 8-month-old boy from Newark, Ohio, suffocated in July 2007 after the drop side of his crib detached due to a broken stop tab on the lower track. An 8-month-old boy from Richmond, Ind., suffocated in October 2003 after broken hardware allowed the drop side to detach from his crib's headboard in one corner. A 6-month-old boy from Staunton, Va., suffocated in September 2002 after two missing screws allowed the lower drop side track of his crib to pull away from the headboard post.

The CPSC has received 20 other reports of incidents involving detached drop sides and eight reports of incidents involving detached mattress supports.

The cribs were made by Generation 2 Worldwide, which went out of business in 2005. The CPSC believes that more than 500,000 cribs were sold. They were available nationwide at furniture and other stores, including Buy Buy Baby, Kmart, Wal-Mart.

Crib owners should contact the place of purchase for information on remedies including refunds, replacements and store credit. CPSC says owners should contact the agency if they have difficulty getting a remedy.
